Fairy Tail: Natsu?!

Natsu comes back from a few-year long job request, but something seems a little off with him, like something's missing. Strange things happen along the way; I would tell you what they are, but you have to read to find out.

I love how the description's all like:
"You know I would tell you about what happened, I really would but... Eh read to find out I won't spoil nothin'! Don't look at me like dat *shoves fan fic in face* READ IT!"
